Method of forming layers on a support

A method of forming a silicon rubber layer on a photosensitive layer formed on a moving support by a coating device and hardening said silicon rubber layer on said photosensitive layer by polymerization, comprising:

• (a) conveying said support to pass near said coating device without coming in contact with said coating device;
• (b) disposing a hardenable silicon rubber solution in a form of a hardenable silicon rubber layer from said coating device onto said photosensitive layer on said support;
• said hardenable silicon rubber solution having been prepared to start polymerizing by mixing an unhardenable silicon rubber solution with a polymerization inducer, said hardenable silicon rubber layer having a lower surface which faces said photosensitive layer and an upper surface opposite to said lower surface;
• and said coating device having a first release point at which said upper surface leaves said coating device and a second release point at which said lower surface leaves said coating device;
• (c) overlaying said first release point with a solvent, thereby syuperimposing a solvent layer on said upper surface of said hardenable silicon rubber layer;
• (d) overlaying said second release point with an unhardenable silicon rubber solution which has not been prepared to start polymerization, thereby superimposing an unhardenable silicon rubber layer on said lower surface of said hardenable silicon rubber layer;
• and
• (e) applying said superimposed layers onto said photosensitive layer on said support so that a hardened silicon rubber layer is formed on said photosensitive layer.
