PROCESSED SUBSTRATES HAVING WATER-REPELLENT AREAS IN PATTERNS, PROCESS FOR PRODUCTION THEREOF, AND PROCESS FOR PRODUCTION OF MEMBERS HAVING PATTERMS MADE OF FUNCTIONAL MATERIAL FILMS

摘要

To provide a treated substrate having a high contrast water repellent region on its surface, and a process for producing it. A treated substrate having a pattern of a water repellent region on a surface of a substrate, characterized in that the water repellent region is made of a water repellent cured film obtained by curing a curable composition containing an organopolysiloxane (A1) having hydrogen atoms bonded to silicon atoms and a photocurable group, or an organopolysiloxane (A2) having hydrogen atoms bonded to silicon atoms and having no photocurable group and a compound (B) having a photocurable group, and further optionally containing a photocuring-accelerating compound (C).
