Abstract:

The method for forming an image which comprises I). providing a mesh fabric substrate, and II). coating said substrate with a light sensitive screen printing composition which comprises in admixture A). at least one substantially water soluble binder resin component comprising an admixture of polyvinyl alcohol and polyvinyl acetate in an amount of from about 33% to about 90% polyvinyl alcohol and from about 10% to about 67% polyvinyl acetate based on the weight of the resin component, in sufficient amount to bind the composition components in a substantially uniform film when the composition is coated on a substrate and dried; and B). a photosensitive component in sufficient amount to substantially, uniformly photosensitize the composition, C). sufficient water to form a substantially homogeneous admixture; and III) drying the composition; and IV) imagewise exposing the composition to sufficient actinic radiation to provide a latent image on the coated substrate; and V) removing the nonimage areas of the compositions by developing with water alone.
