摘要:
A color filter ink used for color filter production using an inkjet method includes a colorant and a liquid medium for dissolving and/or dispersing the colorant therein. When a product containing a cured epoxy adhesive is left undisturbed and sealed in the liquid medium for 6 days at an environmental temperature of 70° C. and under atmospheric pressure, the epoxy adhesive has a swelling ratio of 35% or less. Further, when a product containing a cured urethane adhesive is left undisturbed and sealed in the liquid medium for 6 days at an environmental temperature of 70° C. and under atmospheric pressure, the urethane adhesive has a swelling ratio of 160% or less.
摘要:
A pigment dispersion includes a color pigment represented by Formula (I): wherein R1 to R8 are independently selected from the group consisting of hydrogen, an alkyl group, and a halogen; a polymeric dispersant having, via a linking group covalently linked to its polymeric backbone, at least one pending chromophore group; and the at least one pending chromophore group is a chromophore group occurring as a side group on the polymeric backbone and not a group in the polymeric backbone itself or occurring solely as an end group of the polymeric backbone; and the at least one pending chromophore group is represented by the Formula (II): wherein L is a linking group forming a covalent bond with the polymeric backbone; and R1 to R8 are independently selected from the group consisting of hydrogen, an alkyl group, and a halogen.

摘要:
This invention is directed to a coating composition comprising a film forming binder, one or more pigments, and a graft copolymer suitable for use as a pigment dispersant for forming dispersion of said pigments in said coating composition, wherein said graft copolymer comprises a polymeric backbone and macromonomer side chains attached to the polymeric backbone, and an acetoacetyl amine pigment anchoring group attached to the polymeric backbone, the side chains or both the polymeric backbone and the side chains. The coating composition can further comprise a quaternary ammonium pigment anchoring group attached to the polymeric backbone of the graft copolymer.
摘要:
A pigment dispersion with improved rheology useful for forming solventborne paint compositions is disclosed. The dispersion comprises a copolymer pigment dispersant having at least one quaternary ammonium functional group; a pigment having a pH below 7.0; and an organic liquid carrier. The dispersion is particularly useful for forming colored exterior finishes for automobiles and trucks.
