公式(I)的化合物中,r为1或2的数字;s为1至1000的数字;R为公式(II)的基团;或者R为未取代或取代的萘基、蒽基、菲基或杂环基团;R1、R2、R3、R4和R5各自独立地为氢、未取代或取代的苯基或C1-C12烷基;如果s为1,则A为公式(III)的表面活性基团;或者如果s为1,则A为表面活性基团A0;或者如果s为大于1的数字,则A为公式(III)的基团,其中n对应于数字s;或者如果s为2,则A为基团A1;例如,A0为未取代或取代的C6-C30烷基、C6-C30烯基、C6-C30炔基或C6-C30芳基烷基;A1为未取代或取代的C6-C30亚烷基、C6-C30亚烯基、C6-C30亚炔基或C6-C30芳基亚烷基;n为1至1000的数字;m为0至100的数字;p为0至10000的数字;x为1至10的数字;如果r为1,则Y为二价基团;如果r为2,则Y为三价基团;如果A具有定义A0,则Y为单键;G1、G2、R13、R14、R15、R16、R17、R18、R19、R20、R21和R22例如为C1-C18烷基;特别适用于在固化涂层过程中在表面积累的光引发剂。
