Abstract: PURPOSE:To enhance color forming sensitivity and stabilize a developed color image, by providing a thermal recording layer comprising an electron-donative colorless dye and a phenol compound having a specified substituent group and functioning as an electron-acceptive compound, on a support. CONSTITUTION:An electron-donative colorless dye and an electron-acceptive compound of formula I (Ar is a subtd. or unsubtd. phenyl, Y is a halogen, nitrile group, nitro or a 1-4C alkyl, an m is an integer of 0-2) are placed into a ball mill, a sand mill or the like together with an about 10% aqueous solution of a water-soluble high molecular weight compound, and are dispersed by pulverizing to a particle diameter of several micrometers, thereby preparing a coating liquid. The coating liquid is applied to a support such as a paper and a plastic film by use of a blade, an air knife or the like, followed by drying and a smoothening treatment to obtain a recording material.

Abstract: PURPOSE:To cover widely the wave area for emission of semiconductor laser with a good sensitivity to obtain superior stability and film processability, by a method wherein an information recording layer contains a specific silicon naphthalocyanine compound. CONSTITUTION:An information recording layer contains a silicon naphthalocyanine compound shown by a formula (I) (where R1 and R2 may be either the same or different and represent 4 or more C branched alkyl, alkenyl, or cycloalkyl). This silicon naphthalocyanine compound can be easily obtained by performing the reaction of dihydroxy(2,3-naphthalocyanate)silicon with a branched alcohol shown by R1OH, R2OH. Because the compound has branched chain alkyl or alkenyl, an optical information recording medium has superior light absorption characteristics to a wavelength of 780-830nm. Furthermore, the compound having a solubility in a general-purpose organic solvent such as halogenated hydrocarbon, aromatic hydrocarbon, and ketone compound can dissolve in these solvents to be coated on a substrate in film form by a spray or roller coating etc.
