Abstract
A textured substrate comprising: a first side comprising discrete regions and a continuous region extending between the discrete regions and a second side comprising discrete portions corresponding to the discrete regions and a continuous portion corresponding to the continuous region and a second side comprising discrete portions corresponding to the discrete regions and a continuous portion corresponding to the continuous region. Each discrete region comprises an outer section and sidewall sections extending outwardly from the adjacent continuous region to the outer section. Polymer particles are deposited on at least one of the first side or the second side. At least a section of each polymer particle defines a raised edge.
