Ohp film for plotter

Abstract

Abstract PURPOSE:To attain to enhance the fixing property of aqueous ink by containing a binder comprising polyvinyl alcohol having specific properties and a particulate matting agent having a specific particle size in the coating layer applied and formed to the upper surface of a film comprising a transparent synthetic resin material. CONSTITUTION:A matting agent 4 is compounded in a ratio of 0.5-10% by wt. of a binder 3 and, if the compounding ratio is 0.5wt% or less, the compounding effect of the matting agent 4 is not developed and, if exceeds 10wt%, the transparency of a film is lost. A silica powder or crystalline cellulose with a particle size of 0.01-20mum is used and, if the particle size is 0.01mum or less, the compounding effect of the matting agent 4 is not developed and, if exceeds 20mum surface unevenness becomes large to a necessary degree or more. If the saponification degree of polyvinyl alcohol s the binder 3 is 50mol% or more, hydrophilicity increases and water comes to the real solvent thereof and it becomes impossible to prepare a coating agent applicable to a film main body 1 and, if a polymerization degree exceeds 600, the viscosity of said polyvinyl alcohol becomes too high and processability becomes hard.
