Abstract
A sports ball includes an inflatable ball or a non-inflatable ball. A photosensitive layer is provided on an outer side of the non-inflatable ball. The inflatable ball includes an inner bladder. An outer side of the inner bladder is bonded to a patch layer through an adhesive layer. A valve core is fixed and penetrates from an inner side of the inner bladder to an outer side of the patch layer, such that the inner side of the inner bladder communicates with the outer side of the patch layer through the valve core. A spacer groove is formed between the outer side of the inner bladder and the patch layer. A sealing strip is bonded to an inner side of the spacer groove; and the photosensitive layer is provided on the outer side of the patch layer. The photosensitive layer includes UV photochromic powder.
