Claims21
A mold release agent, comprising:
- (1) a component (A), which is at least one compound selected from a phosphoric acid ester compound represented by formula (I) or a salt thereof:
- wherein, in formula (I):
- R1 is each independently at each occurrence a hydrogen atom or a monovalent organic group;
- X1 is each independently at each occurrence a single bond, an oxygen atom, a group of —NR3—, or a divalent organic group;
- R3 is a hydrogen atom or an alkyl group having 1 to 20 carbon atoms;
- Xa1 is each independently at each occurrence a single bond or an oxygen atom;
- PE1 is each independently at each occurrence a group of the following formula:
- —(CxH2xO)n1—;
- x is each independently an integer of 1 to 6 for each unit in parentheses with n1;
- n1 is each independently at each occurrence in a range of 1 to 20;
- Xb1 is each independently at each occurrence a single bond or an alkylene group having 1 to 6 carbon atoms;
- and
- α is 1 or 2, and
- (2) at least one further component selected from the group consisting of the following components (B1), (B2), (B3), and (C):
- (B1):
- at least one compound having a number average molecular weight of 250 or more and represented by formula (II):
- wherein, in formula (II):
- R2 is each independently at each occurrence a hydrogen atom or a monovalent organic group;
- X2 is each independently at each occurrence a single bond, an oxygen atom, a nitrogen atom, or a group of by —NR3—;
- R3 is a hydrogen atom or an alkyl group having 1 to 20 carbon atoms;
- Xa2 is each independently at each occurrence a single bond or an oxygen atom;
- PE2 is each independently at each occurrence a group of the following formula:
- —(CyH2yO)n2—;
- y is each independently an integer of 1 to 6 for each unit in parentheses with n2;
- n2 is an integer;
- Xb2 is each independently at each occurrence a single bond or an alkylene group having 1 to 6 carbon atoms;
- and
- β is 1 or 2,
- (B2):
- a polyorganosiloxane having, as a main constituent, at least one structure selected from the group consisting of a trifunctional unit siloxane of the following formula (V) and a tetrafunctional unit siloxane of the following formula (VI):
- wherein, in formula (V), R11 is a chain or cyclic alkyl group having 1 to 12 carbon atoms,
- (B3) silicone oil, and
- (C) a polymer having a constituent unit derived from a compound of formula (III):
- wherein, in formula (III):
- Rf is each independently at each occurrence a linear or branched fluoroalkyl group or fluoroalkenyl group having 1 to 6 carbon atoms;
- R41 is a divalent organic group;
- and
- R42 is each independently at each occurrence a hydrogen atom or a methyl group.
