a) a polymer having a first repeating unit of formula (IA) derived from a monomer of formula (I): wherein: represents a position at which the bonding takes place with another repeat unit;a is an integer from 0 to 3;b is an integer from 1 to 4;c is an integer from 1 to 4;R1 is selected from hydrogen, methyl, ethyl, n-propyl, i-propyl or n-butyl; b) a photo active compound containing a diazo-quinone moiety of formula (A): c) an epoxy compound containing one or more oxirane groups; and d) an additive selected from:
a compound of formula (IV): wherein d and e are integers from 1 to 4;f and g are integers from 0 to 4;R2 and R3 are the same or different and independently of each other selected from hydrogen, methyl, ethyl, linear or branched C3-C6alkyl, C3-C8cycloalkyl, C6-C10aryl or C7-C12aralkyl; orR2 and R3 taken together with the carbon atom to which they are attached form a 5 to 8 membered substituted or unsubstituted carbocyclic ring where said substituents are selected from C1-C8alkyl;R4 and R5 are the same or different and independently of each other selected from hydrogen, methyl, ethyl, linear or branched C3-C6alkyl, C3-C8cycloalkyl, C6-C10aryl or C7-C12aralkyl;a compound of formula (V): wherein h is an integer from 1 to 4;i is 1 or 2;R6 independently is hydrogen, methyl, ethyl, linear or branched C3-C16alkyl,C3-C8cycloalkyl, C6-C10aryl or C7-C12aralkyl;a compound of formula (VI): wherein j and k are integers from 1 to 4;l and m are integers from 0 to 4;R7 and R8 are the same or different and independently of each other selected from hydrogen, methyl, ethyl, linear or branched C3-C6alkyl, C3-C8cycloalkyl, C6-C10aryl or C7-C12aralkyl;a compound of formula (VII): wherein n and o are integers from 1 to 4;p and q are integers from 0 to 4;R9, R10, R11 and R12 are the same or different and independently of each other selected from hydrogen, methyl, ethyl, linear or branched C3-C6alkyl; orwhen R13 is —(CH2)r—, one of R9 or R10 and one of R11 or R12 taken together with the carbon atoms to which they are attached form a 5 to 8 membered substituted unsubstituted carbocyclic ring where said substituents are selected from C1-C6alkyl;R13 is —(CH2)r— or phenylene, where r is 1 to 2;R14 and R15 are the same or different and independently of each other selected from hydrogen, methyl, ethyl, linear or branched C3-C6alkyl, C3-C8cycloalkyl, C6-C10aryl or C7-C12aralkyl;a compound of formula (VIII): wherein R16 and R17 are the same or different and independently of each other selected from hydrogen, methyl, ethyl or linear or branched C3-C6alkyl;a compound of formula (IX):or
a compound of formula (X):and
wherein said composition exhibits decreased adhesiveness after exposing to a radiation. |
