Antifouling composition

The invention provides an antifouling composition. The invention also provides an adhesive for an antifouling coating composition, which comprises (I) a hydrophilic copolymer having a glass transitiontemperature of at least 0 DEG C, comprising at least 10 wt% of at least one monomer of formula (I) wherein R is H or CH and R is a C3-C18 substituent having at least one oxygen or nitrogen atom, preferably at least one oxygen atom, or R is a poly (alkylene glycol) chain; and at least one monomer of formula (II), wherein R is H or CH and R is a C1-C20 hydrocarbyl; Less than 15 wt% of a comonomer other than that of formula (I) or (II); (ii) cyclic monocarboxylic acids such as rosin or derivatives thereof; (iii) silyl ester copolymers containing at least 15 wt% silyl ester monomer and / or lessthan 10 wt% of monomers of formula (I) Meth) acrylic polymer. 本发明提供了一种防污组合物。本发明还提供了一种用于防污涂料组合物的粘合剂，包含：(i)具有至少0℃的玻璃化转变温度的亲水性共聚物，其包含至少10重量％的至少一种式(I)的单体，其中R是H或CH，且R是具有至少一个氧或氮原子优选至少一个氧原子的C3-C18取代基或R是聚(亚烷基二醇)链；和至少一种式(II)的单体，其中R是H或C
