Abstract
A resin-coated support sheet favorably employable as a support sheet of image recording material is prepared by the steps of mixing and kneading a polyolefin resin with titanium dioxide under heating to obtain a kneaded mixture, cooling the kneaded mixture, treating the cooled mixture to give pellets, mixing and kneading the pellets with a polyolefin resin under heating to give a diluted mixture, extruding the diluted mixture through a slit of an extruder die, and coating the extruded mixture on a support sheet, wherein the step for giving the diluted mixture starts within 30 minutes after the kneaded mixture is obtained.
Claims6
A process for preparing a resin-coated support which comprises the steps of mixing and kneading a polyolefin resin with titanium dioxide having no hydrophobic compound on its surface under heating to obtain a kneaded mixture containing the titanium dioxide in an amount of 20 to 70 weight %, cooling the kneaded mixture, treating the cooled mixture to give pellets, mixing and kneading the pellets with a polyolefin resin under heating to give a diluted mixture, extruding the diluted mixture through a slit of an extruder die, and coating the extruded mixture on a support, wherein the mixing and kneading step for giving the diluted mixture starts within 30 minutes after the kneaded mixture is obtained.
