Publication number: 20110187786Abstract: An ink contains a plurality of pigments and a plurality of polymers. The plurality of pigments include C.I. pigment yellow 74 and C.I. pigment yellow 128. The plurality of polymers include a polymer A and a polymer B. The C.I. pigment yellow 74 is dispersed by the polymer A. The C.I. pigment yellow 128 is dispersed by the polymer B. A hydrogen bond parameter YA of a unit having the smallest hydrogen bond parameter of the constitutional units of the polymer A and a hydrogen bond parameter YB of a unit having the smallest hydrogen bond parameter of the constitutional units of the polymer B satisfy the relationship of YA<YB. A hydrogen bond parameter PA of the polymer A and a hydrogen bond parameter PB of the polymer B satisfy the relationship of PA<PB.Type: ApplicationFiled: January 27, 2011Publication date: August 4, 2011Applicant: CANON KABUSHIKI KAISHAInventors: Nobuyuki Matsumoto, Fumiaki Fujioka

Publication number: 20110185665Abstract: A method of forming a polymeric building product having a color variation simulating natural building material includes introducing base color pellets having a base color into the barrel and providing a plurality of first colorant shots and second colorant shots. The first and second colorant shots are repeatedly introduced to the base color pellets in an alternating pattern. By repeatedly introducing at least one first colorant shot and at least one second colorant shot to the base color pellets in an alternating pattern, the barrel is in a constant state of purging. As one melted colorant shot is purged and replaced by another melted colorant shot, the melted composition includes streaks in the shape of swirls, wisps, etc., which advantageously creates color variations that simulate natural building material.Type: ApplicationFiled: January 28, 2011Publication date: August 4, 2011Applicant: TAPCO INTERNATIONAL CORPORATIONInventors: Clyde Allen, Timothy Roush, Barton Gentsch, Chad Westenfeld

Patent number: RE45529Abstract: Stone is formed from 5 to 60% by weight of polymerised, low-viscosity, transparent or low-colour-resin, 20 to 90% by weight of spherical alumina trihidrate Al2O3.3H2O containing less regular particles containing, advantageously 0 to 100% by weight of a transparent or translucent substitute of alumina trihydrate, and/or with 0 to 20% or pre-prepared particulate, filled resin of a chosen colour, and/or mineral particles and less than 2% by weight of luminophor. These individual components are mixed intensely whilst extracting included gaseous parts. Extraction is carried out whilst mixing, and/or after mixing, and/or before mixing. The mixture is initiated by introducing a starter and intensely mixing it into the mixture. The mixture is poured into a mould or onto a moving endless belt. The cured synthetic stone is removed from the mould or the hardened composite is taken off the the belt. Synthetic stone can be used in products as a light carrier.Type: GrantFiled: August 21, 2013Date of Patent: May 26, 2015Inventors: Ivan Fucik, Michal Poljakov
