Novel xanthones and thioxanthones of the formula I ##STR1## in which A, X, Y, Z, E and E' are as defined in patent claim 1, are described. A is preferably --S-- and E and E' are preferably bonded in the ortho-position relative to one another. The compounds (I) are suitable, for example, as sensitizers for photocrosslinkable polymers or photocurable compositions, or for use in mixtures with polymers with H donor groups for image formation, in particular electrically conductive coatings and patterns, by means of electroless deposition of metals.
本发明涉及公式I所示的新型黄酮和硫代黄酮,其中A、X、Y、Z、E和E'如专利要求1所定义。A优选为--S--,E和E'优选在相对于彼此的邻位上结合。这些化合物(I)可作为光交联聚合物或光固化组合物的敏化剂,或与具有H供体基团的聚合物混合使用,用于成像形成,特别是通过金属无电镀的方式形成电导涂层和图案。
