Abstract
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.
