Abstract: A spectral photometer including a filter wheel driven by a synchronous motor and an analysis circuit. Interference effects of the power line on the output of the photometer are cancelled by provision of a speed changer to achieve each revolution of the filter wheel in the time required for a set, odd number of power line half-cycles to the motor.

Abstract: Thermally coalescible acrylic resin dispersions comprising particles of single-phase, surfactant-free, random acrylic polymers or copolymers, containing at least 80% by weight of acrylic units, dispersed in a surfactant-free medium that comprises a compatible liquid plasticizer that is nonvolatile at room temperature and is not a monomer of any of the polymeric components. Incorporation of a photopolymerizable, ethylenically unsaturated compound provides photosensitive dispersions useful for making relief and planographic printing plates, photoresists, and the like.

Abstract: A process is provided wherein film (e.g. polyester) which has been dyed by at least one disperse dye, is contacted with textile material in the presence of sufficient heat to cause the dye to sublime or vaporize and transfer some of the dye from the film to the textile material, thereby effecting level dyeing of the textile material. Both the film and textile material have affinity for the dye, and softening points which are higher, and glass transition temperatures which are lower, than the temperature needed to effect sublimation or vaporization and transfer of the dye. Also a process is provided wherein film is continuously dyed with at least one disperse dye and thereafter continuously contacted with a textile material at elevated temperature so as to sublime or vaporize the dye and transfer dye from the film to the textile material.
