Abstract
PURPOSE: To imporve water-resisting qualities, by a method wherein 3-layer consisting of a given resin emulsion and a hydration-resisting agent is laid between a support base substance and a picture receiving layer or a light conductive layer.
CONSTITUTION: An intermediate layer is placed between a support base substance and a picture receiving layer or a light conductive layer, a main component of said intermediate layer being a hydration-resisting agent consisting of emulsion, which is obtained by emulsion-polymerizing a vinyl resin, such as acryl acid ester, methacryl acid ester, etc. by the use of a protection colloid, and a metal complex, such as an amine acid resin, glyoxal, dialdehyestarch, epoxypolyamide, etc. A pigment is mixed to said intermediate layer in order to prevent the occurrence of blocking and improve a smoothness. The intermediate layer is normally 3W20g/m2. The use of a vinyl resin emulsion, which is obtained by emulsion-polymerizing with the protection colloid, allows the sharp improvement of a waterproof.
