Abstract: The present invention is directed to an electronic display stand that can advance through musical notes without interrupting a musician's performance. The stand can be controlled by remote mechanical actuation, the sound of musical notes, or a timed interval. The device can have a display large enough to display a full page of sheet music at one time. A plurality of the devices can be networked to simultaneously display musical notes to a number of musicians. The electronic display stand is a multi-function device that can be used for displaying more than just music.

Abstract: An electrodepositable photoresist composition for producing non-tacky films on an electroconductive substrate comprises an aqueous dispersion of a water-dispersible photosensitive ionic polymeric material and a polyalkylene oxide-modified polysiloxane sufficient to give slip and blocking properties that enables direct placement of a photomask on the resultant dehydrated film. The composition also preferably contains a nonionic unsaturated material and a photoinitiator.

Abstract: A vinyl polymerizable reaction product useful in preparing pigment grind vehicles having improved grind time, viscosity properties and color properties is disclosed. The reaction product can be prepared by reaction of an ester with isopropenyl-.alpha.,.alpha.-dimethylbenzylisocyanate. The resulting product is a urethane ester which can be homopolymerized or copolymerized with other vinyl monomers. The invention is also directed toward the resulting polymeric grind vehicle and pigment pastes made therewith.

Abstract: A high throw power electrodeposition system with improved rupture voltage is disclosed. The electrodepositable coating includes an active hydrogen-containing ionic resin and a gamma hydroxy urethane curing agent, such as a curing agent having the structural feature: ##STR1## The gamma hydroxy urethane curing agent can be prepared by reacting a polyisocyanate with a 1,3-polyol, and in particular with 2,2,4-trimethylpentane-1,3-diol. The composition can also include a curing agent having an alkyl urethane structural feature which can be the reaction product of a polyisocyanate and a blocking agent which is a fatty alcohol. A method for coating a conductive substrate with the above-described composition is also disclosed. The method includes passing an electric current between the conductive substrate serving as a first anode and a second anode to deposit the composition and the conductive substrate.

Abstract: A cationic microgel dispersion and the use of the dispersion in the method of cationic electrodeposition is disclosed. The dispersion is prepared by a process comprising dispersing in aqueous medium a mixture of a cationic polyepoxide-amine reaction product and a polyepoxide crosslinking agent and heating the mixture to a temperature sufficient to crosslink the mixture to form said cationic microgel dispersion. The dispersion can be formulated with ungelled cationic resins to form an aqueous resin dispersion which is suitable for use in the process of cationic electrodeposition providing for improved edge coverage and crater control.

Abstract: A cationic resin containing blocked isocyanate groups which is suitable for use in electrodeposition is disclosed. The cationic resin is derived from an epoxy resin and contains in the resin molecule cationic salt groups, active hydrogen groups and blocked isocyanate groups. The blocked isocyanate groups are incorporated into the resin molecule by reacting the epoxy resin with a compound selected from the class consisting of mercapto compounds and acid group-containing compounds where the compounds also contain blocked isocyanate groups. The resin can be formulated into an electrocoating composition which is free of lead and yet provides outstanding corrosion resistance when electrodeposited over steel substrates. The outstanding corrosion resistance can be attained when the substrate has not been given a chrome rinse which is conventional in pretreating the steel substrate before electrodeposition.

Abstract: Curable compositions comprising blends of active hydrogen-containing polymers and curing agents therefor are disclosed. The blends comprise 5 to 60 percent by weight of a free radical initiated addition polymer prepared from a mixture of monomers comprising:1) an epoxy monomer represented by the formula: ##STR1## where R stands for tertiary aliphatic hydrocarbon group having 4 to 26 carbon atoms,2) a polymerizable alpha, beta-ethylenically unsaturated carboxylic acid, and3) optionally at least one other polymerizable alpha, beta-ethylenically unsaturated monomer.Also present in the blend is 10 to 50 percent by weight of an acrylic copolymer different than the addition polymer mentioned above prepared from a mixture of monomers comprising:1) a monomer of the formula: ##STR2## where R.sub.2 is a polymerizable unsaturated hydrocarbon group, R.sub.3 is hydrogen or C.sub.1 to C.sub.4 alkyl, n=2 to 4 and2) at least one other unsaturated monomer copolymerizable therewith.
