An alkali-soluble polymer, and a positive photosensitive resin composition containing the polymer are provided to improve solvent resistance, water fastness, acid resistance, alkali resistance, heat resistance, transparency and the adhesion to a substrate. An alkali-soluble polymer is obtained by polymerizing a monomer represented by the formula 1 or by copolymerizing the monomer represented by the formula 1 and other radical polymerizable monomer, wherein R1, R2 and R3 are H, or a C1-C3 alkyl group capable of being substituted with F, respectively; R4, R5, R6, R7 and R8 are H, a halogen atom, CN, CF3, OCF3, OH, a C1-C5 alkyl group whose -CH2- can be substituted with -COO-, -OCO- or -CO-, or a C1-C5 alkoxy group whose H can be substituted with a halogen atom; and at least one of R4 to R8 is OH. |
