Method for manufacturing thermal transfer image-receiving sheet support and method for manufacturing thermal transfer image-receiving sheet

A method for manufacturing a thermal transfer image-receiving sheet support comprising a first resin layer on a first side of a substrate and a porous film layer on an opposed second side of the substrate through a second resin layer, wherein the method comprises:

• a first step of supplying a first resin to the first side of the substrate and passing the substrate between a cooling roller A and a rubber roller A to form the first resin layer, and
• a second step of stacking a porous film on the second side of the substrate, not having the first resin layer formed thereon, through a second resin, and passing the substrate between a cooling roller B and a rubber roller B to form the second resin layer and the porous film layer;
• or
• wherein the method comprises:
• a first step of stacking the porous film on the second side of the substrate through the second resin and passing the substrate between a cooling roller B and a rubber roller B to form the second resin layer and the porous film layer, and
• a second step of supplying the first resin to the first side of the substrate, not having the second resin layer and the porous film layer formed thereon, and passing the substrate between a cooling roller A and a rubber roller A to form the first resin layer,
• wherein a surface of the cooling roller A has a ten-point average surface roughness (Rz) in a range of 5 to 30 μm,
• wherein a surface of the cooling roller B has a ten-point average surface roughness (Rz) in a range of 0 to 3.0 μm,
• wherein the rubber roller A has a rubber hardness in a range of 60 to 95, as measured with a durometer (Type A), and
• wherein the rubber roller B has a rubber hardness in a range of 50 to 80, as measured with a durometer (Type A).
