ABSTRACT:
The phenol compound of the present invention can be readily produced by, for example, reacting glyoxal, glutaraldehyde or crotonaldehyde with particular phenols. The phenol compound of the present invention is useful not only as a developer but also as an antioxidant for, e.g., synthetic resins and as an intermediate in the production of medicines or agricultural chemicals.
The heat-sensitive recording material of the present invention, which contains the phenol compound as described above, shows little discoloration of the developed color and little coloration of the ground even at a high temperature and high humidity. Thus it is highly superior to conventional ones.
