Title:
ELECTROPHOTOGRAPHIC TRANSFER PAPER AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH04139455
Kind Code:
A
Abstract:

PURPOSE: To lower overlap feeding in a high-speed machine and to minimize the curling by fixing as well as to improve the efficiency of operations by specifying the weighing, ash and Bekk smoothness of the photographic transfer paper.

CONSTITUTION: A sizing agent of an alkenyl succinic anhydride system or a sizing agent of an alkyl ketene dimer system as at least the sizing agent and calcium carbonate as loading material are incorporated into this paper. The weighing is specified to 60 to 90g/m2, more preferably 63 to 83g/m2, the ash to 3 to 20%, more preferably 5 to 15%, and the Bekk smoothness to 15 to 70 seconds, more preferably 20 to 60 seconds on both surfaces. The conditions expressed by formulas I, II are satisfied when the Bekk smoothness on the front surface side is designated as BA (second), the ash as KA(%), the Bekk smoothness on the rear surface side as BB(second) and the ash as KB(%). The photographic transfer paper which has the low overlap feed rate during feeding and transporting and has the lower degree of curling after fixing is obtd. in this way.
