    Abstract: Novel photopolymers having as photocrosslinking radicals Alpha -substituted maleimido groups of the formula:

    wherein Ar stands for a cyclic group of aromaticity and R1 for a hydrogen atom or cyano group. These photopolymers can be produced by introducing the Alpha -substituted maleimido groups into a backbone molecular chain of a linear polymer or copolymer according to a reaction known per se, such as amidation, imidation, esterification, quaternization or nuclear substitution.

    Abstract: A photosensitive emulsion which contains an emulsion containing a film-forming polymer compound and a photo-crosslinkable polyvinyl alcohol partly having one photo-crosslinkable structural unit, and which further contains: 1) an aliphatic alcohol containing 8 carbon atoms as a defoaming agent; or 2) a dispersion medium comprising a mixture of 95 to 50 wt% of water and 5 to 50 wt% of one or more lower aliphatic alcohols selected from the group consisting of methyl, ethyl, n-propyl and i-propyl alcohols; or 3) an acetylenic glycol compound or acetylenic alcohol compound as a defoaming agent. This emulsion serves to prevent uneven coating.

    Abstract: Photosensitive emulsion contains (A) emulsion contg. (a) a film-forming polymer, (B) photo-crosslinking polyvinyl alcohol contg. photo-crosslinking constitutional unit of formula (I), (IV) or (V) and (C) acetyleneglycol series or acetylene alcohol series cpd. as antiformer. In formulae, A is gp. (II) or (III); R1 is H, alkyl or aralkyl and may contain OH, carbamoyl, ether bonding or unsatd. bonding; R2 is H or lower alkyl; X- is anion; m is 0 or 1; n is integer of 1-6; B is aromatic or heterocyclic contg. at least one kind of polar gp.. Pref. cpd. (C) is, e.g., 2,4,7,9-tetramethyl -5-decyne-4,7-diol or its ethyleneoxide adduct or 3,6-dimethyl-4-octyne -3,6-diol and is used in a concn. of 0.01-5, pref. 0.1-1.0 wt.% based on total amt. of photosensitive emulsion. Mixed ratio of (A) to (B) is 100:10-200 by wt. as solid content.
