Embodiment 1

[0308] Synthesis of 4-(4-Hydroxyphenylthiomethyl)-N-phenylbenzamide (Compound No.XII-248)

[0309] Into a 200 ml 4-necked flask equipped with a stirrer and a thermometer, 1.34 g (10.6 mmol) of 4-mercaptophenol, 0.7 g (10.6 mmol) of sodium hydroxide, and 50 ml of methanol were added at room temperature. After confirming that potassium hydroxide was dissolved, the internal temperature was cooled to 10°C, 2.6 g (10.6 mmol) of 4-chloromethyl-N-phenylbenzamide was added, and the mixture was stirred at room temperature for 3 hours. After the reaction was completed and hydrochloric acid was formed, 50 ml of water was added, and the precipitated crystals were filtered to obtain 3.0 g of 4-(4-hydroxyphenylthiomethyl)-N-phenylbenzamide. The yield was 84%. The melting point is 220-222°C.

Embodiment 2

[0311] Synthesis of 4-(4-hydroxyphenylthiomethyl)-N-(2-hydroxyphenyl)benzamide (Compound No.XII-267)

[0312] Except using 4-chloromethyl-N-(2-hydroxyphenyl)benzamide to replace 4-chloromethyl-N-phenylbenzamide in Example 1, carry out the same reaction as in Example 1 . The melting point is 152-156°C.

Embodiment 3

[0314] Synthesis of 4-(4-hydroxyphenylthiomethyl)-N-(3-hydroxyphenyl)benzamide (Compound No.XII-264)

[0315] The same reaction as in Example 1 was carried out except that 4-chloromethyl-N-(3-hydroxyphenyl)benzamide was used instead of 4-chloromethyl-N-phenylbenzamide in Example 1. The melting point is 218-222°C.

Abstract

An object of the present invention is to provide a novel phenolic compound, and a recording material containing the same, which is excellent in storage stability. The object can be achieved by a phenolic compound represented by the formula (I): [wherein m represents an integer of 0 to 2; R1 and R2 each independently represents a C1-C6 alkyl group or a C1-C6 alkoxy group; p and q each independently represents an integer of 0 to 4; t and u each independently represents 0 or 1 and do not simultaneously represent 0; and X represents a group represented by any of the formulas (II) to (VII): (wherein R3, R4, R5, R6, R7, R8, R9, R10 and R11 each independently represents a hydrogen atom or a C1-C6 alkyl group; a represents an integer of 1 to 6; b represents an integer of 0 to 4; and c represents an integer of 0 to 6)] and a recording material containing the same.

Description

[0001] This application is a divisional application of the invention patent application with Chinese application number 03805660.7 (the invention title of the original application is "phenolic compounds and recording materials using phenolic compounds", and the filing date of the original application is March 13, 2003) . technical field [0002] The present invention relates to a novel phenolic compound and a recording material containing the phenolic compound and having good storage stability. Background technique [0003] A recording material that develops color by the reaction of a chromogenic dye and a developer can be recorded in a short time with a relatively simple device without tedious processing such as developing and fixing, so it is widely used in output records such as faxes and printers The heat-sensitive recording paper used or the pressure-sensitive copy paper used to copy multiple receipts at the same time, etc. These recording materials not only require ra...
