Abstract: A photosensitive multi-layer material comprising a base and a photosensitive layer which has a polyamide binder and is soluble or dispersible in an alcoholic solvent contains two layers between the base and the photosensitive layer, namely (a) an adhesion-promoting layer, adjacent to the base, which is derived from a polyurethane binder, prepared by reacting a hydroxyl-containing epoxy resin and a polyisocyanate, and a pigment combination in which a white zinc sulfide pigment is the essential constituent, and (b) an adhesive layer, adjacent to the photosensitive layer, which consists of a baked mixture of an alcohol-soluble copolyamide and a melamine-formaldehyde resin.

Abstract: A process for the preparation of etherified or non-etherified aminoplast resins, wherein an aminotriazine of the general formula (I) (I) where X is hydrogen, alkyl, phenyl, alkylphenyl or -NH2, is reacted with a beta -hydroxyaldehyde of the general formula (II) (II) where R', R'' and R''' are identical or different and each is hydrogen or alkyl, or R'' and R''', together with the alpha -carbon atom, are a cyclopentane or cyclohexane ring, and R'' and/or R''' can be hydroxyalkyl and R'' can be phenyl, the reaction being carried out in the presence of not less than one alcohol and an acid catalyst for the preparation of etherified aminoplast resins and in the presence or absence of an acid catalyst for the preparation of non-etherified aminoplast resins. The aminoplast resins prepared according to the invention can be used as surface-coatings raw materials.

Abstract: A photosensitive multi-layer material comprising a base, which may or may not be provided with an adhesion-promoting layer, and a photopolymerizable layer, consisting of a mixture of a photoinitiator, a binder and a photopolymerizable monomer, possesses, between the base and the photopolymerizable layer, an adhesive layer of a hardened mixture of a binder and an etherified melamine-formaldehyde condensate, hardenable at 60 DEG -120 DEG C.
