摘要： A thermoplastic resin-based functional film obtained by a process which comprises the following steps either A or B and C:

A. mixing 10 to 95 parts by weight of a thermoplastic resin (a) having a melting point or melting starting temperature Tm a , 5 to 150 parts by weight, per 100 parts by weight of said thermoplastic resin (a), of a solvent (c) and 5 to 90 parts by weight of a functional substance having a property-change temperature Tb equal to or lower than Tm a at a temperature lower than Tb to form a mixture, keeping the mixture at a temperature lower than Tb for at least 10 minutes, kneading the mixture at a temperature lower than Tb into a substantially uniform kneaded mixture and shaping the substantially uniform kneaded mixture into a film at a temperature lower than Tb,
B. preliminarily mixing 10 to 95 parts by weight of a thermoplastic resin (a) having a melting point or melting starting temperature Tm a and 5 to 150 parts by weight, per 100 parts by weight of said thermoplastic resin (a), of a solvent (c) at a temperature lower than Tm a , keeping the resultant preliminary mixture at a temperature lower than Tm a for at least 10 minutes, adding 5 to 90 parts by weight of a functional substance having a property-change temperature Tb equal to or lower than Tm a to the above preliminary mixture, kneading the resultant mixture at a temperature lower than Tb to form a substantially uniform kneaded mixture and shaping the substantially uniform kneaded mixture into a film, and
C. removing the solvent (c) from the film.
