摘要： PURPOSE:To obtain a thermal recording material superior in shelf stability of image and non-image portion, by a method wherein a specific amino compound is contained in the thermal recording material made of an aromatic isocyanate compound and an imino compound reacting with the aromatic isocyanate compound under heat to develop color. CONSTITUTION:In a thermal recording material consisting of an aromatic isocyanate compound and an imino compound which reacts with the aromatic isocyanate compound under heat to develop color and has at least one C=NH group, an amino compound shown by a formula I is contained. In the formula I, R1, R2, R3, and R4 represent hydrogen, halogen, alkoxy group, or alkyl group, and R1 and R3 may form a sulfonyl group in common with each other. By using the aforesaid amino compound, a thermal recording material superior in shelf stability of image and in shelf stability of non-coloring portion (sheet surface) can be obtained.

摘要： PURPOSE:To enhance image preservability, especially, light fastness, in a recording material consisting of a specific fluorene dye precursor and a developer for allowing said precursor to form a color through the reaction therewith, by compounding an aromatic isocyanate compound and a specific imino compound. CONSTITUTION:An imino compound has at least one group represented by formula 1 and is represented by formula II (wherein phi is an aromatic compound residue capable of forming a conjugated system along with adjacent C=N) and is a colorless or light- colored compound solid at ambient temp. Each of the imino compound and an aromatic isocyanate compound is used in a amount of 1% or more by wt. of a dye precursor. When a developed color image obtained from a fluorene dye precursor represented by formula III (wherein R1, R2, R3, R4, R5 and R6 are respectively a lower alkyl group) and a developer is exposed to sunrays, the image is deteriorated within a short period and the sufficient absorption of a near infrared region is not obtained but, by using the imino compound and the aromatic isocyanate compound, the obtained image holds the absorption of the near infrared region even when exposed to sunrays for a long period of time and the deterioration thereof is markedly prevented by the interaction of both compounds.
