Zusammenfassung:	A coloured photosensitive material comprises a styrene and/or diene polymer randomly grafted with side chains contg. photopolymerisable double bond and colourant side chains. Used in prodn. of printing plates. The colourant is chemically attached to the photopolymerisable material and is not therefore removed by the developer which may be an organic solvent. The side chains contg. photopolymerisable double bond are pref. of formula: R(YC-CX)q-C(=O)-(R1)n- (where R is H, 1-10C aliphatic group, furfural or an aromatic gp. opt. substd. by alkyl, alkoxy or nitro; R1 is O, S or a hydrocarbon gp. opt. contg. O or S; X and Y are H, halogen, CN, NO2 or phenyl and n and q are 1 or 2). The colourant side chains are pref. anthraquinone, spiropyran or quinoline gps. POLYMERES PHOTOSENSIBLES COLORES CONSTITUES D'UNITES STYRENIQUES ETOU DIENIQUES SUR LESQUELLES SONT FIXES DES CHAINONS LATERAUX PHOTORETICULABLES ET DES CHAINONS LATERAUX COLORANTS.ILS SONT OBTENUS PAR REACTION D'UN POLYMERE MULTIFONCTIONNEL AVEC UN ACIDE OU HALOGENURE D'ACIDE COMPORTANT UNE DOUBLE LIAISON PHOTOPOLYMERISABLE ET UN HALOGENURE DE COLORANT.UTILISATION NOTAMMENT COMME COMPOSANTS PHOTOSENSIBLES DE MATIERES DE REPRODUCTION PHOTODURCISSABLES.
