Abstract
A process for producing a heat-sensitive recording paper is disclosed. The process involves pretreating base paper by a high-frequency corona discharge. The base paper treated in this manner can be utilized in producing a heat-sensitive recording material by providing a heat-sensitive layer thereon. By subjecting the base paper to the high-frequency corona discharge treatment the base paper can be uniformly coated with a heat-sensitive recording material without leaving any blank spaces thereon.
Claims3
A process for producing a heat-sensitive recording paper which comprises pretreating a base paper by a high-frequency corona discharge and then applying an aqueous-type coating solution for forming a heat-sensitive recording layer to the base paper, wherein the high-frequency corona discharge treatment is carried out utilizing a discharge frequency in the range of 5 to 200 KHz and is carried out such that the product of the discharge electric current and the discharge voltage applied to a unit width is in the range of 0.5 KVA/m.sup.2 to 50 KVA/m.sup.2.
