New vinyl compounds of the general formula ##STR1## are provided, wherein A is --CO-- or --SO.sub.2 --, v is 0 or 1, w is 0 or an integer of 1 to 6, x is 0 or 1, y is 2 to 6 and z is 1 or 2, at least one of w and x x being a positive integer. The vinyl compounds are useful as cross-linking agents for hydrophylic colloids, especially for gelatine in gelatino silver halide emulsion layers and other layers in photographic material.
提供了一般式为##STR1##的新乙烯化合物,其中A为--CO--或--SO.sub.2--,v为0或1,w为0或1到6的整数,x为0或1,y为2到6,z为1或2,至少其中一个w和x为正整数。这些乙烯化合物可用作水性胶体的交联剂,尤其适用于明胶在明胶银卤化物乳胶层和摄影材料中的其他层。
