A photosensitive composition becoming sticky upon exposure to light which comprises (a) a salt of a diazonium compound represented by the formula
wherein R, and R2 are independently -H, -CH3, -OCH3 or
but R1 and R2 cannot be
at the same time; and R3 and R4 are independently a straight-chain lower alkyl group, and (b) a salt of an aromatic diazonium compound having no -OH group directly bonding to a benzene ring, has an improved sensitivity because it contains the salt of the compound represented by the above formula. By using said photosensitive composition, there is provided a process for forming a pattern of powder coated layer excellent in light sensitivity.
一种光敏组合物,在光照下会变得粘稠,该组合物包括 (a) 由式表示的重氮化合物的盐
其中 R 和 R2 独立地为-H、-CH3、-OCH3 或
但 R1 和 R2 不能同时为
R3和R4独立地为直链低级烷基,以及(b)没有-OH基团直接键合到苯环上的芳香族重氮化合物的盐。通过使用上述光敏组合物,提供了一种形成感光性极佳的粉末涂层图案的工艺。
