| An improved method for imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is a water-soluble halotriazine dye. The dye is reacted with a hydrophilic monomer to prepare a reactive dye containing predominantly monofunctionality. The monomer is then subjected to polymerization in the presence of a homogeneous solution of the reactive dye in the monomer under conditions to yield the hydrophilic polymer from which the lens is formed. The dye becomes bonded to the polymer during polymerization. The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens. Furthermore, the lens does not need to be washed with aqueous base to bond the dye to the lens. | ||||||

| A hydrophilic polymer, e.g., provided as a contact lens, is tinted by a method which incorporates a reactive dye into the polymer during formation of the latter. Following physical entrainment of the reactive dye in the polymer, the polymer is contacted with an aqueous solution of a base which catalyzes the reaction of the dye with the polymer. In this way, the dye becomes permanently covalently bound to the polymer. | ||||||

| An improved method is disclosed of imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is composed of a water-soluble compound essentially free of ethylenic unsaturation. A homogeneous solution of the dye in a hydrophilic monomer is prepared, the solution is subjected to polymerization conditions to yield a hydrophilic polymer from which the lens is formed, and the dye dispersed within the polymer is bonded to the polymer by contact with aqueous base prior to final hydration.The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens. | ||||||

| A method of tinting an unhydrated contact lens involves the steps of providing an unhydrated contact lens; providing a dyestuff solution; providing a printing block comprising a hydrophilic polymer material containing a dye complexing agent capable of noncovalently bonding the dyestuff; placing the dyestuff solution onto the printing block; contacting the unhydrated contact lens and the printing block for a time sufficient to allow the dyestuff solution to diffuse to the lens; and removing the lens from the printing block. | ||||||

| PURPOSE: To obtain a polymerizable monofunctional dye of high purity by adding a base to an aqueous solution of a hydrophilic monomer and reacting the monomer with a water soluble halotriazine dye. CONSTITUTION: To an aqueous solution of a hydrophilic monomer are added 0.01-0.75 wt.% of a water soluble triazine dye and a Lewis base in a molar amount equal to or greater than the molar amount of the dye to react in the presence of 0.05-1 wt.% of a free radical initiator at 35-70°C for 16-32 hr, and subsequently the pH of the mixture is adjusted to 5-8.
