The invention relates to a crosslinkable acrylate polymer composition comprising a first polymer having Tg of 50 to 100° C. and a second polymer having Tg of −10 to 25° C., wherein the composition has an acid number of 1-30 mg KOH/g, or the composition has an acid number of 1-39 mg KOH/g and at least one of the first polymer and the second polymer comprises 0.1-5 wt % of monomer units having a crosslinkable functional group based on the weight of the composition, and a primer prepared thereof. The invention also relates to use of said primer for preparing beer bottle label paper.
