ABSTRACT:
Sheet material useful in the preparation of draftsmen's and engineers' plans and drawings comprises a base support, preferably of a stable polyester film, bearing a translucent pencil- and ink-receptive coating comprising finely-divided silica pigment dispersed throughout a binder matrix which is essentially a cross-polymerized reaction product of a mixture of a relatively low molecular weight acrylic or methacrylic ester vinyl monomer, a drying oil acrylate, and a blend of polyene and polythiol radiation curable polymers. The coating composition is substantially devoid of volatile solvent vehicle, yet is readily set to a functional drafting surface by exposure to actinic radiation, such as ultraviolet light.
