A thermosensitive recording material comprises a thermally reactive layer (14) separated from a receiver stock (10) by an undercoating layer (12). The undercoating (12) has ingredients which inhibit the penetration of a thermally reactive layer (14) into the receiver stock (10) and which also enhances the opaqueness and brightness of the receiver stock (10). The undercoating (12) comprises a water resistant binder, a hollow sphere pigment, and a viscosity modifier. As such, the undercoating (12) comprises about 10-50% styrene-butadiene, about 35-85% styrene-acrylic, and about 1-20% viscosity modifier selected from the group consisting essentially of polyvinyl alcohol, zinc stearate, sodium polyacrylate, paraffin wax, fumed silica, carboxy methyl cellulose and Natrasol. <IMAGE> |
