Embodiments of the optical disc and its manufacturing method are disclosed in the present invention. In one embodiment, the optical disc comprises at least two plastic substrates 1 comprising an adhesive layer and a data layer disposed between the plastic substrates, wherein the at least one substrate 1 is based on the total weight of the reading side substrate. A reading surface substrate comprising at least about 0.01% by weight of a colorant, said reading surface substrate having a UV bond index of at least about 0.5. The method of making an optical disc comprises forming a first plastic substrate comprising at least about 0.01% by weight of a colorant based on the total weight of the first plastic substrate, wherein the UV bonding index of the first plastic substrate is adjusted to at least about 0.5, Disposing a data layer between the first plastic substrate and the second substrate, adhering the first plastic substrate to the second plastic substrate using an adhesive layer, and curing the adhesive layer. |
