摘要：
The invention relates to a crosslinkable material containing a polymer onto which chromophores are laterally grafted, characterized in that each chromophore is within a polymer unit which corresponds to the following formula (I): ##STR1## in which: X represents a part of the polymer chain,A is a group --NO.sub.2, --CN, --C(CN).dbd.C(CN).sub.2 or --SO.sub.2 R.sub.4, R.sub.4 being a C.sub.1 to C.sub.6 alkyl,D is a nitrogen, sulphur or oxygen atom,R.sub.1 is a hydrogen atom or a C.sub.1 to C.sub.6 alkyl if D is a nitrogen atom, or nothing if D is a sulphur or oxygen atom,R.sub.2 is a C.sub.1 to C.sub.6 aliphatic alkyl group,and E is a group chosen from --OH, --O--CO--(CH.sub.2).sub.n --COOH, --O--W, --O--CO--R.sub.3 O--W and --O--R.sub.3 --O--W, n being an integer between 2 and 6, W being a photodimerizable group and R.sub.3 being a C.sub.1 to C.sub.6 alkyl,and the said material additionally containing complementary anchoring functional groups capable of attaching themselves to E during the crosslinking.
