Abstract
The present invention provides an image receiving sheet applicable to an over head projector (OHP) and a process for forming an OHP image. The image receiving sheet is capable of forming a yellow image providing a parallel-ray transmittance (Y) of 50% or more when the transmittance density (X) is in a range from 0 to 1.0 by electrophotography. The image receiving sheet is capable of forming a yellow image providing a haze value (Z) of 40% or less when the transmittance density (X) is in a range from 0 to 1.0 by electrophotography.
Claims16
An image receiving sheet printable by electrophotography and applicable to an overhead projector (OHP), the image receiving sheet being capable of forming a yellow image providing a parallel-ray transmittance of 50% or more when the transmittance density is in a range from 0 to 1.0 by electrophotography.
An image receiving sheet printable by electrophotography and applicable to an overhead projector (OHP), wherein the following expression 1 is established between the transmittance density and the parallel-ray transmittance when the transmittance density is in a range from 0 to 0.6;
- Expression 1
- Y≧{34/(X+1.2)}+57
- where X represents the transmittance density and Y represents the parallel-ray transmittance, provided that 0≦X≦0.6.
