DEVELOPER DISPERSION LIQUID AND PRESSURE-SENSITIVE RECORDING DEVELOPMENT SHEET USING SAME

摘要

PROBLEM TO BE SOLVED: To prevent the fixing of stain in a drying process and improve operation properties in the manufacture of a pressure-sensitive record development sheet. SOLUTION: A 3 g/m2 developer dispersion liquid is applied and dried on a PET film of 40 μm thickness to form a film, and when a face opposite to another face whereon the PET film is formed is brought into contact with a hot metal and left thereon for 10 seconds and the metal surface temperature at which the film is turned transparent is set as T, the temperature T of the developer dispersion liquid is 120 deg.C or higher.
