  • Patent number: 4318952
    Abstract: Decorative articles having a three-dimensional patterned surface are formed employing the different surface tension properties of a wet ink printed pattern and a liquid top coat composition; the difference in surface tension is such that the liquid top coat composition retracts from the wet ink pattern; subsequently the ink is dried and the top coat is dried and cured.
    Type: Grant
    Filed: July 2, 1980
    Date of Patent: March 9, 1982

  • Patent number: 4294021
    Abstract: A method and apparatus for curing of wet resin-coated articles in a curing chamber by means of a vaporous curing agent. The vaporous curing agent is circulated through distribution members having nozzles or openings which are adapted to disperse the curing agent in an angular direction cocurrent with the direction of travel of the articles being passed through the curing chamber. The exhaust is provided near the exit end, and thus a gaseous flow is induced from the inlet through the chamber to the exhaust thereby minimizing the escape of vaporous curing agent through the inlet opening.

  • Patent number: 4169907
    Abstract: A decorative simulated ceramic tile is produced in a method which comprises applying to a flat surface of a non-metallic, porous substrate, an under-coat effective to seal the surface and provide a colored, printable base; printing on the printable base a pattern composed of ink lines of a colored drying ink containing 0.75 to 5% by weight of an organic silicone oil, and allowing the ink to dry; applying to the printable base, a coloring pigment-containing liquid top coat containing from 0.75% to 2.
