Abstract: The present invention relates to a photosensitive composition containing at least one compound selected from the group consisting of N-acyl amino acid derivatives, hydroxycarboxylic acids and their derivatives, condensates of an aliphatic or aromatic aldehyde with a polyhydric alcohol, acylated polysaccharides and metallic soaps. From the photosensitive composition of the present invention, moldings having excellent shape retentivity and/or compatibility of the components thereof with one another can be produced. Therefore, the production of moldings from a composition which has been heretofore impossible is made possible. Particularly a composition having a good moldability during the molding operation can be employed. The composition is useful for the preparation of printing plate materials having a good developability and printing plates, particularly flexible printing plates and flexographic printing plates, having an improved ink solvent resistance.

Abstract: A printing plate formed of a substrate and laminated thereon in the following order a primer layer and a photosensitive layer containing a quinonediazide compound and a silicone rubber layer, wherein the primer layer contains 0.1 to 25% by weight of a quinonediazide group. The printing plate of the present invention is excellent in dot reproduction, hardly causes cracking in the photosensitive layer, and has a wide latitutde in production.

Abstract: Cured elastomers prepared by the reaction of a hydroxyl-terminated polyorganosiloxane with curing agents containing silicon-bonded aminoxy and/or amido groups can be painted when a dialkoxysilane of the formula X'R.sup.1 SiR.sup.2 (OR.sup.3).sub.2 is present in the curable composition. In the foregoing formula R.sup.1 is alkylene, haloalkylene or oxyalkylene, R.sup.2 and R.sup.3 are individually hydrocarbon, alkoxy-hydrocarbon or halohydrocarbon radicals and X' is glycidoxy, mercapto, acryloxy, methacryloxy, NH.sub.2, --N(C.sub.2 H.sub.5).sub.2 or --N(H)CH.sub.2 CH.sub.2 NH.sub.2.
