The present invention provides a new process for recording an image by using the above mentioned phenomenon. The process comprises (i) inserting an anisotropic molecular oriented film between two polarizing film of which polarization directions are parallel or perpendicular to each other, so that the anisotropy of said anisotropic molecular oriented film forms an angle of 45.degree. to the polarization directions of said polarizing film, and (ii) completely or incompletely degrading the anisotropy of an image portion in said anisotropic molecular oriented film.

Process for recording an image, a film structure therefor and its

Disclosed is a water-borne coating composition having improved pigment dispersibility. The water-borne coating composition comprises a pigment and a water dispersible or water soluble resin, wherein said pigment is preliminary ground with crosslinked resin particles having ionic groups on the surface.
