US 2017/0014278 Al  11  Jan. 19, 2017  the diaper, two 6.5 pound weights are placed on either end  of the sheet in order to mimic the weight of the baby on top  of the diaper.  [0095]  Synthetic urine is then prepared according to the  following recipe as disclosed in U.S. Pat. No. 6,772,708 to  Klofta. The synthetic urine is then heated to a temperature of  38°  C. in order to mimic body temperature of urine. 40  milliliters of this heated synthetic urine is then measured  into a graduated cylinder. This 40 milliliters of the synthetic  urine is then poured into the polycarbonate cylinder on top  of the diaper at a rate of approximately 2 to 3 milliliters per  second. After all of synthetic urine is poured into the  cylinder, a stop watch is started. An additional fort~ milli› liters is poured into the cylinder at a rate of approximately  2 to 3 milliliters per second at both the 5 and 10 minute time  points as measured using the stop watch.  [0096]  The color of the wetness indicator is then moni› tored (as can be seen through the backsheet) at the following  time points after the stop watch is started after the first 40  milliliter volume of synthetic urine is poured into the  cylinder: 1) 2 minutes and 2) 5 minutes. After the second  dose of 40 milliliters of synthetic urine is added at the 5  minute point, observations are recorded at the 10 minute  point, and after the third dosed of 40 milliliters is added at  the 1 O minute point, final observations are recorded at the 15  minute point. The color can be measured using the following  6-point scale of Oto 5:  Any colorant leaching into the surrounding areas in_ the  vicinity of the wetness indicator is simply recorded with a  yes or no designation. A "yes" denotes the observation of  some of the wet state color residing in the areas around the  wetness indicator. A "no" denotes the presence of no wet  state color within the surrounding areas.  [0109]  Examples A-H  [0104]  After this range of time is met, the tin_ie i_s recor~ed  and the diaper is flipped over so the wetness md1cator side  faces up for easy viewing by the naked eye. Both the color  of the wetness indicator (as viewed through the backsheet),  as well as the areas located next to it are inspected to  determine dye retention within the wetness indicator, as well  as dye leaching into areas residing next to the wetness  indicator. Even though the color could be measured spec› trophotometrically, a visual grading system can also be  applied. The color of wetness indicator can be graded  according to the following scale:  [0103]  The colorant retention test is performed on the  identical diaper used in the colorant kinetic test. The diaper  comprising the wetness indicator continues to be sand› wiched between the polycarbonate sheets described in the  colorant kinetic test method (above) and continues to be  weighted down for a total of 2 to 16 hours.  C. Colorant Retention Test Method:  [0102]  5 denotes greater than 90% of the backsheet film  area corresponding to the wetness indicator area chang› ing to the wet state color.  [0097]  O denotes no color change of the wetness indi› cator through the backsheet film remaining in its dry  state color, such that the wetness indicator remains  completely yellow over the backsheet film area corre› sponding to the wetness indicator area;  [0098]  1 denotes less than 10% of the backsheet film  area corresponding to the wetness indicator area chang› ing to the wet state color;  [0099]  2 denotes 10-40% of the backsheet film area  corresponding to the wetness indicator area changing to  the wet state color;  [0100]  3 denotes 41-60% of the backsheet film area  corresponding to the wetness indicator area changing to  the wet state color;  [0101]  4 denotes 61-90% of the backsheet film area  corresponding to the wetness indicator area changing to  the wet state color; and  [0108]  3 denotes greater than 90% of the final wet state  color remaining within the wetness indicator through  the backsheet film.  [0107]  2 denotes 51 % to 90% of the final wet state color  remaining within the wetness indicator through the  backsheet film; and  [0106]  1 denotes 10% to 50% of the final wet state color  remaining within the wetness indicator through the  backsheet film  [0105]  O denotes less than 10% of final wet state color  residing within the wetness indicator through the back› sheet film;  Component  First Binding Agent 1  First Binding Agent’  HLB Modifier’  Stabilizer 4  Stabilizer 5  Second Binding agent 6  Second Binding agent  7  Colorant 8  Colorant 9  Surfactant 10  Anti-Oxidant 11  CTH Stability Test  (5 days at 75% Relative  Humidity & 40°  c.)
