Image-receiving elements utilizing lamellar pigment materials

An image-receiving element for a diffusion transfer product which comprises a support carrying an image-receiving layer and a substantially white layer positioned between said image-receiving layer and said support, said substantially white layer comprising a lamellar pigment dispersed in a matrix material, said lamellar pigment having at least one layer with a geometric thickness within the expression:

• ##EQU4## where:
• T is the geometric thickness of the layer, .lambda. represents a wavelength or wavelength range of radiation in the visible region of the spectrum and n is the refractive index of the layer material and is at least 1.7;
• any layer adjacent said one layer having a geometric thickness of a value also within said expression but comprising a layer material having a refractive index different from the refractive index of said one layer.
