Abstract
The present invention relates to a process for preparing polyvalent metal salts of salicylic acid resin, comprising reacting salicylic acid or its derivative and styrene or its derivative in the presence of zinc salt of organic carboxylic acid and/or polyvalent metal compound at 50 to 200 °C
to prepare the reaction product, and reacting the reaction product with polyvalent metal compound; an aqueous dispersion where the polyvalent metal salt of resin is dispersed in water; and to a color development sheet prepared from the polyvalent metal salts of salicylic acid resin.
to prepare the reaction product, and reacting the reaction product with polyvalent metal compound; an aqueous dispersion where the polyvalent metal salt of resin is dispersed in water; and to a color development sheet prepared from the polyvalent metal salts of salicylic acid resin.
Description
POLYVALENT METAL SALTS OF SALICYLIC ACID RESIN
AND PRO(:ESS FOR THE PREPARATION THEREOF
Field of the Invention s The present invention relates to a polyvalent metal salt of salicylic acid resin, which is used as a color developer for recording material such as pressure-sensitive copying paper, and to a process for the preparation thereof. Furthermore, it relates to an aqueous dispersion and a color development sheet prepared from the polyvalent metal salts of salicylic io acid resin.
Background of the Invention It is known that metal salts of salicylic acid derivative axe useful as color developers for pressure-sensitive copying paper, and numbers of is preparation processes and uses thereof were proposed. For example, 1 ) 3,5-disubstituted salicylic acid derivative is prepared from the reaction of 2;,4-disubstituted-phenol derivative with carbon dioxide by Kolbe-Schmitt reaction (Japanese Patent Publication No. 76-25174 and LT.S. Patent No. 3,983,292). In this method, however, ao two-step process is needed to prepare 3,5-disubstituted salicylic acid derivative from phenol, and high-temperature high-pressure facility is required in the reaction with carbon dioxide. In addition, in case of using as color developer the metal salts of 3,5-disubstituted salicylic acid derivative such as zinc salt of 3,5-di(a-as methylbenzyl)salicylic acid, developed image might be lost on water contaca.
