Similarly, the heterocoagulating step may at least partly be carried out at a pH that can facilitate the coalescence or merging of the organic polymer latex particles for the formation of the coating layer over the shell of the primary capsule. Depending on the identity of the organic polymer latex particles used, the pH applied to aid the coalescence or merging of the organic polymer latex particles may vary. Accordingly, a suitable pH range may be used. For example, the heterocoagulating step may be carried out at a pH of from about 2 to about 11, from about 2.5 to about 10.5, from about 3 to about 10, from about 3.5 to about 10 or about 2, about 2.5, about 3, about 3.5, about 4, about 4.5, about 5, about 5.5, about 6, about 6.5, about 7, about 7.5, about 8, about 8.5, about 9, about 9.5, about 10, about 10.5 or about 11. In various embodiments, the method and/or the heterocoagulation step further comprises physically curing the organic polymer latex particles. For example, the curing may be carried out by using at least one of temperature or pH as a curing means. In various embodiments, curing the organic polymer latex particles does not comprise chemically curing/cross-linking the organic polymer latex particles. Accordingly, the method and/or heterocoagulating step may therefore also comprise one or more of: changing/adjusting/regulating a pH of the mixture, changing/adjusting/regulating a temperature of the mixture, or curing the organic polymer latex particles in the mixture optionally at room/ambient temperature or below room/ambient temperature. For example, this may include raising/increasing the pH of the mixture optionally by about 5 points, about 5.5 points, about 6 points, about 6.5 points, about 7 points, about 7.5 points, about 8 points, about 8.5 points or about 9 points. The changing/adjusting/regulating a pH of the mixture and/or curing the organic polymer latex particles in the mixture may comprise raising/increasing the pH of the mixture from about 2 to about 11, from about 2.5 to about 11, from about 3 to about 11, from about 3.5 to about 11, from about 4 to about 11, from about 2 to about 10.5, from about 2.5 to about 10.5, from about 3 to about 10.5, from about 3.5 to about 10.5, from about 4 to
