A solid dispersion of pigment in granular form may include: at least one pigment; and at least one cold-water-soluble modified starch. A method for preparing an aqueous composition including at least one pigment may include: combining the at least one pigment, at least one cold-water-soluble modified starch, and water. A process for preparing a solid dispersion of pigment in granular form may include: mixing at least one pigment, at least one cold-water-soluble modified starch, and water to form a paste; and/or grinding the paste and evaporating at least part of the water to obtain the solid dispersion. A process for using at least one cold-water-soluble modified starch may include: preparing a solid dispersion of pigment in granular form by combining at least one pigment, the at least one cold-water-soluble modified starch, and water; and/or using the at least one cold-water-soluble modified starch as a carrier agent in the solid dispersion.

The present invention provides an optical film, which is excellent in ultraviolet absorption capability at 380 nm with little bleed-out, comprising a resin containing a triazine compound represented by the following general formula (I). (In the formula, R1-R6 may be a hydrogen atom; hydroxyl group; or an organic group selected from among an alkyl group, alkoxy group, dialkyl amino group, alkyl carbonyloxy group, aryl group, arylated alkyl group, aryloxy group, arylated alkyloxy group and an aryl carbonyloxy group having 18 or less carbon atoms, independently. However, the alkyl part of these organic groups may be substituted by a hydroxyl group, halogen atom, cyano group or nitro group, interrupted by an oxygen atom, sulfur atom, carbonyl group, ester group, amide group or imino group, or have a double bond, and these substitutions, interruptions and double bonds may be combined).

摘要:
The process of this invention can be utilized to stabilize tin-coupled rubbery polymers. This process involves adding a chelating diamine to the rubbery polymer after the tin coupling has been carried out. This invention more specifically discloses a process for improving the stability of a tin-coupled rubbery polymer which comprises adding a tertiary chelating amine to the tin-coupled rubbery polymer subsequent to the time at which the tin-coupled rubbery polymer is coupled. The tertiary chelating amine will preferably be a tertiary chelating alkyl 1,2-ethylene diamine, such as N,N,N',N'-tetramethylethylenediamine.
