NEW MATERIAL:A compound shown by the formula I or formula II (R 1 is H, alkyl, alkoxy, or halogen; R 2 is H, alkyl, cycloalkyl, aryl, aralkyl, or tetrahydrofurfuryl). EXAMPLE: A compound shown by the formula III. USE: For a liquid crystal display element. Having improved solubility in and stability to liquid crystal. Having the maximum absorption at 700W900nm. PREPARATION: For example, an anthraquinone compound shown by the formula IVor V is reacted with a compound shown by the formula VI(e.g., 2-nitro- thiophenol, etc.) in the presence of an alkali in DMF.

6 PREPARATION OF COLORED CONTACT LENS JP28875493 1993-10-25 JPH06235887A 1994-08-23 FURANKU EFU MOROTSUKU; JIEEMUSU DEII FUOODO
PURPOSE: To provide a process for producing a colored contact lens which does not require the immersion of the lens into an aq. soln. of dyes, for the purpose of coloring the lens to a desired color after polymerizing a hydrophilic monomer, the lens material. CONSTITUTION: The soft hydrogel contact lens is colored by uniformly dispersing the dyes into the lens. Water-soluble halotriazine dyes are used for the dyes. The dyes are brought into reaction with the hydrophilic monomer, in order to prepare the reactive dyes contg. just one functional group. The monomer is then polymerized in the soln. of the hydrophilic monomer homogeneously dispersed with the reactive dyes described above, under the conditions under which the hydrophilic polymer constituting the lens is formed. The dye is bonded to the polymer during the polymn.

8 OLIGOMER MATERIAL JP2000397420 2000-12-27 JP2002194003A 2002-07-10 TAKIMOTO HIROSHI
PROBLEM TO BE SOLVED: To obtain an oligomer material excellent in the coloring concentration, transparency, light resistance, weather (environmental gas) resistance, bleeding resistance and safety as coloring of a plastics member, electrophotographic toner, ink-jet recording, color filter or cosmetic. SOLUTION: This material has a recurring unit represented by formula (I) [wherein D is a color residue, ultraviolet-absorbing residue or antioxidant residue; X is a direct bond or a linking group; l is 0 or 1] and/or formula (II) [wherein A is an anionic color residue, ultraviolet-absorbing residue or antioxidant residue].

10 PIPERAZINE ANTHRAQUINONE DYE FOR SYNTHETIC FIBER JP847680 1980-01-28 JPS56104967A 1981-08-21 KITAO TEIJIROU; MATSUOKA MASARU
NEW MATERIAL:Piperazine anthraquinone dye of the formula I (where R is H or acyl group). EXAMPLE:1-Hydroxypiperazino[2,3,-C] anthraguinone. USE:A dye which is capable of dyeing a synthetic fiber, e.g., of polyester, polyamide, etc., in fast purple or blue color. PREPARATION:1-hydroxypiperazino[2,3-C] anthraquinone of the formula II (where the group corresponding to R of the formula I is H) is obtained by adding cupric chloride dihydrate and ethylene diamine to quinizarin and stirring the mixture. Also, a dye whose R (as shown in the formula I) is acyl group is obtained by adding acyl halide to a compound to the formula II and stirring the mixture.
