Abstract: A composition for electrodeposition paint, comprising (a) a water-dispersible and electrophoretic fluoropolymer obtained by neutralizing with a basic compound at least a part of carboxyl groups of a carboxyl and hydroxyl group-containing fluoropolymer having an acid value of from 5 to 30 and a OH value of from 30 to 150 and (b) an aminoplast, which are dispersed in an aqueous medium in a weight ratio of component (a)/component (b) of from 50/50 to 97/3.

Abstract: The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by depositing a specified amount of a layer of copper on said ferrous metal substrate, applying an adhesive thereover comprising an interpolymer containing about 50 to about 99% by weight of a conjugated diene, about 1-45% by weight of a heterocyclic base and 0 to about 40% by weight of at least one additional copolymerizable monomer, thereafter contacting said adhesive with the rubbber to be bonded and bonding by heat and pressure.

Abstract: The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by depositing a loosely adhered layer of copper on said ferrous metal substrate, applying an adhesive thereover comprising an interpolymer containing about 50 to about 99% by weight of a conjugated diene, about 1-45% by weight of a heterocyclic base and 0 to about 40% by weight of at least one additional copolymerizable monomer, thereafter contacting said adhesive with the rubber to be bonded and bonding by heat and pressure.

Abstract: A method for coloring aluminum and aluminum alloys comprising passing an alternating current from the article of aluminum or aluminum alloys having an oxidized film thereon through an aqueous solution of one or more salts of one or more metals of Group VIII of the periodic table, and thereafter passing a direct current through an aqueous solution of electrolyte utilizing the aluminum material as the anode wherein said solution may have a conductivity of more than 10 .mu..OMEGA..sup.-.sup.1 cm.sup.-.sup.1, be the same as the one used when employing the alternating current or contain a water-soluble resin. The electrolyte is free of added acid.

Abstract: A polyglutamic ester having hydrogen containing groups which are reactive with an --NCO group and a hydroxyl polyester or a hydroxyl polyether are reacted with an organic diisocyanate and the resulting block polymer in an organic solvent is coated on a cloth to prepare a synthetic leather.

Abstract: The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by using as the adhesive an interpolymer comprising a conjugated diene and a heterocyclic nitrogen base and containing about 5-180 parts of silica filler per 100 parts by weight of interpolymer. Further improvement is achieved by using a rubber containing about 0.025 to about 1.0 parts by weight of a cobalt compound, calculated as cobalt metal, per 100 parts of rubber.
