The photosensitive resins are used mainly for making coating solution of various photosensitivities. The coating solution which has the quick photosensitivity, the wide latitude of development, the excellent resolving power, the good coatability, the strong alkali resistance and the high length of run can be compounded matching our photosensitive resins with filming resins.

Our company can produce the photosensitive resins for positive PS plate according to customer’s samples and requirements.
