Resin composition and uses of the same

A resin composition, comprising:

• (A) a maleimide compound with indane structure;
• and
• (B) a component having ethylenically unsaturated double bond(s), which is selected from the group consisting of compounds represented by formula (I), compounds represented by formula (II), and combinations thereof,
• wherein,
• each A is independently —O—, —S—, or —N(R1)—, wherein R1 is H, a C1-C20 hydrocarbyl, a C1-C20 halogenated hydrocarbyl, or a group formed by substituting a part of the C1-C20 hydrocarbyl or halogenated hydrocarbyl with at least one of O and S;
• each R is independently an unsubstituted or substituted divalent nitrogen-containing heteroaromatic ring;
• each X is independently
• wherein R2 and R3 are independently a direct bond or a C1-C4 alkylene, Ar1 and Ar2 are independently an unsubstituted or substituted divalent aromatic hydrocarbyl, L is a direct bond, —O—, —S—, —N(R4)—, —C(O)—O—, —C(O)—NH—, —S(O)—, S(O)2—, —P(O)—, a C1-C20 alkylene, a C1-C20 halogenated alkylene, a divalent cardo structure, or an unsubstituted or substituted divalent C5-C30 alicyclic hydrocarbyl, R4 is H, a C1-C20 hydrocarbyl, or a C1-C20 halogenated hydrocarbyl, p is an integer from 0 to 5, and each Ar1 can be identical or different when p is 2 or more;
• each Y is independently a group containing ethylenically unsaturated double bond(s);
• m is an integer from 1 to 100;
• and
• n is an integer from 1 to 100.
