Abstract:
1. A pattern formed body comprising a wettability pattern consisting of an unexposed area whose contact angle to a liquid having a surface tension of 40 mN/m is 10° or more, and an exposed area whose contact angle to a liquid having a surface tension of 40 mN/m is 9° or less, wherein the pattern formed body is obtained by exposing the surface of a wettability variable layer of a wettability variable substrate in a pattern, under a condition that the wettability variable layer is facing to a photocatalyst layer containing a photocatalyst, thus obtained pattern formed body does not contain the photocatalyst, the wettability variable substrate comprising a wettability variable layer, on a substrate, which the wettability is varied by being exposed under the condition that the wettability variable layer is facing to the photocatalyst layer containing a photocatalyst, and the wettability variable layer before an exposure: contains an organopolysiloxane which is a co-hydrolysis condensation polymer obtained using (A) one type or two or more types of organopolysiloxane precursors represented by Y does not contain the photocatalyst; and wettability of a surface of the wettability variable layer has a contact angle to a liquid having a surface tension of 40 mN/m is 10° or more.
