ABSTRACT:
A laminated non-slip liner or mat comprises a first lower laminate layer, the undersurface thereof having printed thereon a pattern of relatively high friction material; a second laminate upper layer of material with upper and lower surfaces is supported by the first layer, with an adhesive layer between the first and second layers, bonding the top face of the first layer to the bottom face of the second layer. The lower, first laminate layer serves as a barrier between the pattern of relatively high friction material and the adhesive. Preferably, the pattern of relatively high friction material is a high density matrix of printed latex, polyvinylchloride, or polyethylene projections which may include a tackifying agent to enhance the coefficient of friction of the projections. The second laminate layer may be a printed vinyl sheet. The improved liner or mat has the unexpected benefit of not adhering to fine finish surfaces of oil based paints, lacquers and linoleums. By making the laminated layers of substantially equal thickness, the tendency to curl, when unrolled may be substantially reduced. The lower layer can be of material selected from an extremely wide range of unwoven and woven materials, both synthetic and natural.
