    Abstract: A resin product wherein a resin B has pillar structures or lamellar structures inside a resin A is moulded by kneading the resin A and the resin B that serves as a base material in an injection moulding machine while heating both of the resins to at least a temperature at which both of the resins are melted at least partially. The resin product is soaked in a solution having higher erosion capability with respect to the resin A than the resin B, thereby dissolving the resin B and forming an uneven structure on the surface. As a result, an uneven structure having various shapes, densities or depths which are precisely adjustable can be formed at low cost. And provided are a resin structure and a production method thereof that can maintain wettability control or optical property control of the moulded article over a long period of time.

    Abstract: A method for manufacturing a microporous film comprising the steps of:

    (a) providing a first polymer which is a hydrophobic thermoplastic polymer and a second polymer which is a hydrophilic polymer or copolymer of N-vinylpyrrolidone;
    (b) dissolving said first and second polymers in a solvent system which is compatible with both polymers, said solvent system comprising a blend of an aprotic organic solvent and an alcohol;
    (c) coating the resulting solution on a support;
    (d) effecting at least a partial drying of the resulting coating; and
    (e) washing the coating in an aqueous medium so as to extract at least 50% by weight of the said second polymer.

    Image accepting members comprising a microporous film made by the above method, and preferably comprising a support which is also microporous.
