Abstract: PURPOSE:To provide a color forming recording material having high absorption within the range from a visible region to a near infrared region and having a high light resistance by providing a recording layer containing a azo compd. represented by a specific general formula and an acidic substance on a support. CONSTITUTION:A predetermined amt. of an azo compd. represented by formula I (wherein X is H, an amino group, an alkyl group or an acyl group, Y is H, halogen, an alkyl group or an aryl group, m is a natural number of 4 or less and A and B are H, an alkyl group or an aralkyl group) and a predetermined amt. of an acidic substance are mixed. The obtained mixture is compounded with an aqueous soln. of a binder such as polyvinyl alcohol and ground to prepare a coating soln. This coating soln. is applied to a support such as fine paper and dried to form a recording layer, thus obtaining a color forming recording material. As a concrete example of the azo compd., there is 4-aminoazobenzene or 4-(N-methylamino)azobenzene and, as examples of the acidic substance, there are phenol, naphthol, acid clay, kaolin and the like.

Abstract: PURPOSE:To obtain the color developing recording material capable of developing practicable sufficiently intense color immediately after making color developing operation and enabling readout of information through instruments using lights of all the wavelengths by incorporating a specified diamine derivative and an oxidant, and an organic acid material solid at normal temperature. CONSTITUTION:The recording material contains the oxidant, the organic acidic material solid at normal temperature, and the diamine derivative represented by formula I in which each of A and B is, independently, aryl; X is arylene, and each of R and R is, independently, H, lower alkyl, aryl, or aralkyl. It is preferred that the oxidant is a quinoid type electron receptor, thus permitting practicable sufficiently intense color to be developed and the color developing part to have strong absorption in the wide region from visible to near infra wavelengths, and therefore, readout of information to be made by instruments using all the wavelengths.

Abstract: PURPOSE:To produce the titled compound useful as a raw material for asymmetric polymer, additive for polymer production, etc., in high yield, by reacting naphthalenes in the presence of a peroxide and an acid and, if necessary, acylating the reaction product. CONSTITUTION:1,1'-Binaphthols of formula II (e.g. 2,2',6,6'-tetraphydroxy-1,1'- binaphthyl) can be produced by reacting naphthalenes of formula I (R is H or alkyl; R is H, hydroxy, alkyl, alkoxy or halogen) (e.g. 2,6-dihydroxynaph thalene) in the presence of a peroxide (e.g. hydrogen peroxide) and an acid (e.g. sulfuric acid) and, if necessary, reacting the product with an acylation agent (e.g. formic acid and acetic acid). The process can be performed without brominating a naphthalene compound as a raw material, using decreased amount of catalyst and preventing coloring of the product.
