A set of carbonless recording sheets wherein each of the individual sheets of the set may be separately stacked with sheets which are identical thereto without the danger of offsetting or inadvertent reproduction occurring through that stack. The sheets become operative only when assembled into the manifolded set. The central, intermediate sheets of the manifolded set are each coated front and back with respective chemicals which are incapable of reacting with one another to produce a color. The set includes at least two different types of intermediate sheets, one of which has a front coating capable of reacting with the back coating of the other to produce a color and vice versa. Generally, the manifolded set will include a top sheet which has a back coating only, one or more intermediate sheets which have a front coating capable of reacting with the back coating of the next adjacent higher sheet to produce a color and a back coating which is capable of reacting with the front coating on the next adjacent lower sheet to produce a color, and a bottom sheet having a front coating which is reactive with the back coating of the next adjacent higher intermediate sheet to produce a color.
