The present disclosure relates to thermoplastic polymeric microspheres comprising a thermoplastic polymer shell surrounding a hollow core, in which the thermoplastic polymer shell comprises a copolymer of a monomer of Formula 1:wherein:each of A1 to A11 are independently selected from H and C1 to C4 alkyl, in which each C1-4 alkyl group can optionally be substituted with one or more substituents selected from halogen, hydroxy and C1-4 alkoxy;A12 is selected from C1 to C4 alkyl, in which the C1-4 alkyl group can optionally be substituted with one or more substituents selected from halogen, hydroxy and C1-4 alkoxyX is a linking group selected from -O-, -NR″-, -S-, -OC(O)-, -NR″C(O)-, -SC(O)-, -C(O)O-, -C(O)NR″-, and -C(O)S-; andR″ is H or C1-2 alkyl optionally substituted with one or more substituents selected from halogen and hydroxyl.
