Photosensitive stencil materials.

摘要

Stencil materials for use in screen printing are multilayer products, having a film support (1) which carries two or more light-hardenable layers (2; 3) and a peelable cover sheet (4, 5); the layer 3 in contact with the cover sheet (4, 5) has a sufficient thickness and also is sufficiently soft and tacky to be able to absorb the meshes of a printing screen at least to an extent to allow the stencil material to adhere to the screen; the layer 2 nearer the support (1) is relatively harder and non-tacky.
