5 Claims

1. A silane coupling agent having:

a polymerizable group,

a reactive silyl group, and

a spacer group connecting the polymerizable group and the reactive silyl group,

wherein the spacer group is the following spacer group I:

Spacer group I:

—Z¹—NH—C(O)OR³— Formula (I)

wherein, Z¹is a C2-C30 linear or branched saturated aliphatic hydrocarbon group, and has at least one or more of —CH₂—CH₂—O—, —O—CH(CH₃)—CH₂— and —O—CH₂—CH(CH₃)— groups, and R³is a C7-C30 linear or branched alkylene group, and may have one or more of —S—, —NH—, —NRⁿ— wherein Rⁿrepresents an alkylene group, —CH₂—C₆H₄— wherein C₆H₄represents a phenylene group, —C(O)—O—, —O—, —CH₂—CH₂—O—, —O—CH(CH₃)—CH₂— and —O—CH₂—CH(CH₃)— groups.
