  • Patent number: 4210693
    Abstract: The present disclosure relates to decorative flexible sheet goods and a method for making the same, such as sheet vinyl floor and wall coverings, wherein a crinkle finish is created on a decorative pattern on a flexible substrate in varying thicknesses and also in register with said decorative pattern. The method is accomplished by means of printing an actinic radiation curable coating which is essentially solvent-free and comprises at least one organic compound having at least two photopolymerizable ethylenically unsaturated groups per molecule and capable of curing upon exposure to actinic radiation. The actinic radiation cured registered coating serves the novel purpose of creating the desired relief to the pattern in register, and also forms a durable wear layer with superior stain and wear characteristics as well as gloss retention properties.

  • Patent number: 4100318
    Abstract: Application of an actinic radiation curable coating which is essentially solvent free and comprises at least one organic compound having at least two photopolymerizable ethylenically unsaturated groups per molecule to a cushioned vinyl product comprising an expanded vinyl foam and clear vinyl overlay atop a carrier where a decorative pattern is usually present. The coating is fully reacted upon exposure to actinic radiation resulting in a tack-free surface essentially free from imperfections and property weakening voids. The actinic radiation coated cushioned sheet goods has improved stain resistance, gloss retention, scratch and abrasion resistance. The preferred application areas are sheet vinyl floor and wall coverings.
